Definitions

  • the present invention relates to conduits for the transport of a fluid comprising a hydrocarbon.
  • the present invention aims to improve the latter type of pipes. In particular, we seek to improve their resistance to external pressure.
  • the pipe can withstand a high external pressure, greater than 100 bar, so that this pipe can be used in deep offshore.
  • the longitudinal direction referred to in this description shall be understood as the direction the direction X designated in the figures.
  • a transverse direction mentioned in this description should be understood as the direction Y or Z indicated in the figures. These directions are only mentioned to help reading and understanding the invention.
  • conduit of the present invention is to be understood as being a device comprising a tube for conveying fluid at least between an inlet and an outlet, the device may comprise other elements, such as a valve, or taps multiple.
  • FIGS. 1a and 1b have a pipe 1 according to the invention in longitudinal section along an XZ plane and in cross section along a YZ plane.
  • a pipe 1 according to the invention in longitudinal section along an XZ plane and in cross section along a YZ plane.
  • FIG. 1 only one upper half above the X axis is shown, the other lower half being substantially identical by symmetry with respect to the X axis.
  • the pipe 1 comprises a hollow inner tube 2, extending in the longitudinal direction of axis X between a first and second end (1a, 1b) of the pipe.
  • This inner tube 2 comprises an inner surface 2a close to the axis X, and an outer surface 2b further from the axis X.
  • Inside the inner surface 2a extends a cavity 2c between an inlet and a outlet of the cavity at each end.
  • the cavity 2c is adapted to transport the fluid between said inlet and outlet.
  • the figure 1b shows that the pipe 1 has a substantially cylindrical shape, but other forms could be made.
  • the inner tube 2 may be made of an electrically insulating material, for example a polymer.
  • This material may advantageously be a polyamide (PA) or a polyvinylidene fluoride (PVDF).
  • This inner tube 2 can also be made of an electrically conductive material, such as steel. In this case, it will include at least on its outer surface 2b a layer of electrical insulation 2d visible in figure 2 , for example consisting of one of the polymers mentioned above, or of a composite comprising glass or Kevlar fibers embedded in a polymer material of the same type as mentioned above.
  • This electrical insulation layer 2d has a thickness in a transverse direction, for example between 0.5 mm and 10 mm, in particular as a function of the supply voltage V of the heating layer.
  • a thermal insulation layer 10 is applied on this inner tube 2 of the pipe 1, at least one heating layer 3, a thermal insulation layer 10 is applied, spaced means 10a are placed or formed, and an outer tube 11 is placed or formed on said spacing means 10a.
  • the heating layer 3 is a composite comprising at least carbon fibers embedded in a polymer.
  • This polymer may advantageously be a polyamide (PA), or a polyvinylidene fluoride (PVDF).
  • the thickness E p and the angle of inclination a make it possible, during the design, to define the electrical resistance of this heating layer 3, and consequently the consumed electrical power P used to heat the tube 2.
  • the angle of inclination ⁇ can take any value between 0 degrees and 70 degrees. However, for reasons of ease of manufacture and reasons for risks of delamination of the composite with a low angle of inclination value during the bending of the pipe 1 (for example when laying on the seabed), this angle of inclination ⁇ will advantageously be greater than 10 degrees.
  • the coefficient cos 2 ⁇ varies substantially between 0.12 and 0.97, which means that the electrical resistance R of the heating layer 3 may vary over a very wide range by defining only this angle of inclination ⁇ carbon fibers.
  • the heating layer 3 can be manufactured by known means of the type presented in the publication FR-2,873,952 using preformed composite strips, each strip extending in a main direction and comprising carbon fibers embedded in a polymer, said carbon fibers being oriented substantially in said main direction of the preformed strip.
  • the heating layer 3 may be made by a stack of sub-layers, each sub-layer comprising inclined carbon fibers with an angle of inclination ⁇ i predetermined with respect to the longitudinal direction X. Each sub-layer then comprises carbon fibers with an angle of inclination different from the neighboring sub-layer. For example, each underlayer is formed using preformed strips, as explained above. Alternatively, two successive sublayers may have opposite inclination angles to form a diamond grid as viewed from an outer surface of the heating layer 3.
  • Each sub-layer of index i has an inclination angle ⁇ i , a thickness E pi , a mean diameter D moyi , and has an elementary electrical resistance R i .
  • the elementary electrical resistance R i of each sub-layer of index i can be calculated by the preceding formula for calculating a layer having carbon fibers at a single angle of inclination.
  • this heating layer 3 comprising well-distributed carbon fibers in the polymer material of this layer, the heating is more homogeneous around the tube 2.
  • the electric current continues to pass.
  • the carbon fibers cross each other and are at least partly in contact with each other, so that the electric current and the heating remain homogeneous in the heating layer 3. Only the area where the fibers are broken is then affected.
  • Such a pipe 1 is therefore very tolerant to manufacturing defects and handling accidents that may deteriorate locally.
  • Spacing means 10a are placed periodically along the pipe 1 in the longitudinal direction X. Their function is to fix the outer tube 11 at a distance from the inner tube 2 and to protect the heat insulating layer 10 from a high outside pressure to the outside driving 1.
  • These spacing means 10a may be a composite comprising a reinforcing filler embedded in a polymeric material, formed on the inner tube 2 and the heating layer 3.
  • the reinforcing filler may comprise glass or Kevlar fibers to increase the mechanical resistance of these spacing means.
  • these spacing means 10a can be extruded or on the inner tube 2 equipped with the heating layer 3.
  • the thermal insulation layer 10 may be preformed in the form of wide strips of material adapted to be mounted between these spacing means 10a: Each strip has substantially the width of the distance between each spacing means 10a in the longitudinal direction X, and as a length the outer perimeter of the heating layer 3. Each strip of the insulation layer 10 is then wound up around the heating layer 3 between each spacing means 10a.
  • the strips of the insulation layer 10 are for example made of a thermally insulating material, such as a polyurethane foam (PU).
  • this thermal insulation layer 10 is injected by an injection means into the cavities defined by the heating layer 3, the spacing means 10a and the outer tube 11.
  • the spacing means 10a comprise openings in the longitudinal direction so that the successive cavities communicate with each other, and that the material this insulation layer 10 can be injected by said injection means into all the cavities.
  • the material of the insulation layer 10 is advantageously a foam, such as a polyurethane foam (PU).
  • the outer tube 11 may be steel, or be a composite comprising carbon fibers and a polymer, such as polyamide (PA) or polyvinylidene fluoride (PVDF).
  • a polymer such as polyamide (PA) or polyvinylidene fluoride (PVDF).
  • the outer tube 11 may advantageously comprise a composite comprising at least one reinforcing filler embedded in a polymer, the reinforcing filler comprising at least carbon fibers. It is advantageous to use the same polymer for the heating layer 3, the spacing means 10a and the outer tube 11.
  • the inner tube 2 is also advantageously made with the same polymer.
  • Line 1 is a multilayer composite comprising a polymer such as a polyamide (PA) or a polyvinylidene fluoride (PVDF).
  • PA polyamide
  • PVDF polyvinylidene fluoride
  • the outer tube 11 may be manufactured with the same technique as for the heating layer 3. It may comprise a plurality of sub-layers, each sub-layer comprising carbon fibers inclined at a predetermined angle of inclination. In addition, each underlayer may be formed using preformed strips. Additionally, the angle of inclination of an underlayer is of value opposite the angle of inclination of a neighboring or adjacent sub-layer. The angle of inclination of these sub-layers is then advantageously between 20 degrees and 70 degrees.
  • the pipe 1 is very rigid, in particular it can withstand a very high external pressure, for example greater than 100 bar and preferably greater than 200 bar.
  • the angle of inclination will advantageously be between 60 and 70 degrees, and preferably close to 65 degrees.
  • the pipe 1 also withstands very high compressive forces.
  • the angle of inclination is advantageously between 20 and 30 degrees, and preferably close to 25 degrees.
  • the pipe 1 also withstands very high bending forces. It can be wound with a small radius of curvature, for example less than 20 m, and preferably less than 10 m. An angle of inclination between 50 and 70 degrees will be preferred to obtain a small radius of curvature. It can then be used by a large seabed without risk of being damaged during its installation, whether by a so-called "S” laying technique or a so-called "J” laying technique, for which the pipe forms one or more elbows before resting on the seabed.
  • the inner tube 2 may have a small thickness and be made of a less rigid material, that is to say only able to support the manufacture of successive layers on said inner tube 2 and not the constraints of the external pressure to the pipe 1.
  • the heating layer 3 is then at a small distance from the inner surface 2a of the tube 2 and the heating of the transported fluid is more efficient. In addition, power required to heat the fluid is lower.
  • a tube 6 inches in diameter (approximately 15 cm in diameter), comprising 54 layers of carbon fibers embedded in a polyamide PA11 polymer with first sub-layers having angles of inclination at +/- 25 degrees, then second sub-layers having angles of +/- 65 degrees, these sub-layers representing a thickness of 15 mm, has the following mechanical characteristics: resistance to an external pressure of 245 bar, resistance to an internal pressure of the fluid of 1500 bar, and tensile strength of 550 tons.

  • V V / R.
  • the electrical supply means 6 shown comprise a cable 6a in relation to the outside of the pipe 1, and a connecting element 6b coming into contact with the carbon fibers of the heating layer 3 and connected to said cable 6a.

  • the connecting element 6b and the groove 3a have an annular shape around the longitudinal axis X.
  • the groove 3a is located near one end of the heating layer in the longitudinal direction.
  • These assembly means 7 may further be adapted to maintain the supply means 6 of the heating layer 3.
  • the pipe 1 may comprise a temperature sensor intended to be connected to control means for regulating the electric current in the heating layer 3.
  • the temperature sensor may comprise an optical fiber adapted to measure a temperature profile along the pipe 1 in the longitudinal direction X.
